FEATURES

• Unmatched Strength & Durability – Triple heat-treated for extreme toughness under the most punishing race conditions.

• Dynamic “No Holes” Balance – Engineered for smoother operation and reduced vibration at high horsepower levels.
• Lightened for Performance – Through-pin lightning holes reduce rotating mass without sacrificing strength.
